I need help with simplifying fraction expressions

hey what do you need help with in particular?

whats the problem?

my aunt told me how to do it, but the teacher says it is wrong and when I asked someone else they got same answer as my aunt

i do not understand how to multiply and divide fractions

umm how did ur aunt do it?

adding n suctracting them she would find common denominators and then simplify but my teacher says my aunt is wrong

ah ok, well, multiplying is pretty easy: you just multiple the top number of each fraction and the bottom number of each fraction

like this problem 5 3/4 divided by 1 2/3

ah ok, so for that problem you can convert it to a non-mixed fraction

let me re write that one 5 3/4 \[\div\] 1 2/3

so 5 3/4 means 5 whole parts of 4 (20) + 3 parts of 4

that is, 20/4 (since 20/4 is 5) + 3/4 = 23/4

how do I do that?

1 2/3 is saying "I have one set of 3's, and then 2 more"

so that means I have 1*3/3 + 2/3 = 5/3

now when you divide fractions, it's the same thing as multiplying by 1/(originalfraction), which basically means you multiply by the inverse of the fraction by flipping the top and bottom

oh ok see my teacher does not explain it that thorough

so 23/4 divided by 5/3 = 23/4 * 3/5 (I just flipped the 5 and the 3) = (23*3)/(5*4) = 69/20

and that is the answer

i get it know i did be for i get it even better know lol

i was just waching

great! keep in mind you can always check with your calculator that you got the right answer
